## Abstract The effects of samarium on the properties of the anodic Pb(II) oxides films formed on lead at 0.9 V (vs. Hg/Hg~2~SO~4~) in 4.5 mol/L H~2~SO~4~ solution were studied using linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS) and scanning electron micrographs (SEM)

An electrochemical voltammetric analysis of oxide layers formed by anodic polarization of platinum electrodes over the potential range 2.43.0 V has shown that the reduction of the layers produced in pure H,SO, occurs in two well defined waves, whereas the oxides formed by polarization in CNScontaini
The anodic film studied was formed on Pb + 9at.%Bi at 0.9V (vs. Hg/Hg,S03 in 4.5 M H, SO, solution (25Β°C). The change of the phase composition of the anodic film during reduction at -0.91 V (vs. Hg/Hg,SO,) (slightly more positive than that of the reduction potential of PbSO,) was determined by X-ray
